This is a discussion on K&N? within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; So I have a 14' hatch, all stock and was gonna do a simple upgrade like a K&N filter...any thoughts ...

The K&N filter, in theory, will not change the sound and honestly will give you absolutely minimal gains, definitely not anywhere close to beneficial especially if the old filter is brand new... Any bolt on mod that gives you any sort of noticeable change in performance for these cars requires a tune.

There is a thread in the stickies that shows a lot of good first mods to do for your WRX.

It's an aftermarket intake. They have short ram intakes and cold air intakes. The short ram intake is more inside the engine bay as to a CAI which pulls in cooler air from near the wheel well. Yes you would need to tune for it.

I had the k&n on mine for a week...then did my research and took it off. Don't waste your money on the drop in filter.

If you do want a intake, get the cobb once you have their AccessPort to safely run it.

Oh, and torqued performance has a map to run the K&N typhoon intake of you choose that route...

First thing is first. Screw Eric from TP. He's a giant piece of crap who is dangerous to vehicles. He disabled a lot of the safety measures during my tune. He's a rogue tuner whom I had some very off dealings with. I'm not a fan in the least bit.

Secondly, have you ever put a k&n typhoon on, and then had your vehicle checked on a dyno? I have. And it was fine on my vehicle.

What was your research? Was it factual? I had a K&N typhoon for 85,000 miles. 35,000 of it was untuned.

I agree 100% eric is a giant pos did a horrible tune on my car was a really unsafe map and very unprofessional the way he does his business he's just a wannabe tuner.

This is a short ram intake. Replaces your air box, panel filter, snorkus, intake tube and MAF with a cone filter, heat shield, and intake tube.

Only purchase a reputable one. Personally, I'd only purchase K&N Typhoon and COBB SF because both have the heat shields, and a reputation for not having to tune.

Very interesting. I didn't realize the k&n didn't need to be tuned. I was under the impression that the 08+ were very sensitive to any type of intake modification. I'd question the point of adding an intake that made no noticeable amount of change for which a retune would be required. Certainly not questioning your facts at all as you obviously have personal experience with it. Just find it an interesting fact. I would always advise that it would be a good idea to have a method of monitoring or logging data regardless just so that I could tell if there were any bad effects of any mod...just in case of a bad install, leak, etc.
